SPECIFICATION forming part of Letters Patent No. 275,165, dated April 3, 1883.

Application filed October 17, 188i'.

To all 'whom 'it may concern Be it known that I, JOHN E. DONOVAN, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Clothes-Wringers, of which the following is a specification.

My invention relates to a clothes-wringer; and it consists of certain new improvements in the manner of constructing the frame; also,in an improved manner of applying pressure to the upper roller, all of which will be fully set forth in the description of the accompanying drawings.

Figure l is a central vertical longitudinal view of my invention. Fig. 2 is a section on line x x, Fig. 1. Fig. 3 is an end elevation. Fig. 4 is a section on line x fr, Fig. 2. Fig. 5 is a plan view of the brace.

A A represent the end piece of the frame, made ot' a single piece of bent wood, a representing the leg or lower part, b the central portion, on which is supported the lower roll and journal, a', and b the upper overhanging arm supporting the upper roller and journal.

a represents a bow made in the leg to allow it to yield laterally to t over a tub. c" represents the spring-bow supporting the arm b', so as to allow the elastic action of the upper roller.

B represents a leg connected to the framepieceAby means of clamp-boltC,and attached thereto by a dowel, c, which projects into the part b.

D represents the upper roller, secured to shaft d, which journals in the spring-arm b.

E represents the lower roller, connected to shaft e, which journals in boxes attached to the shoulder b of the frame-piece A.

H represents clamp-rods which pass through the shoulder b, arms b', and spring-bar L.

I I represent clamp-nuts for regulating the pressure on the upper roller, D.

d d represent spur-gears upon the rollers shafts at one end, and g g similar gears upon the opposite end.

Bar L is made forked at either end, and rubber or coiled springs m m are inserted in the forks, so as to allow of a yielding mot-ion to the upper roll in operation.

l lrepresent rollers 4inserted in the base of the forks in bar L, to regulate the tension of (No model.)

the spring formed by the forks and to prevent their becoming set.

N N represent journal-boxes; o o, a series of friction-rollers which justtillan annulusformed between the periphery ofthejournal-boxes and the shaft-bearings. The anti-friction rollers relieve the rubber rolls D and E of friction, and avoid nearly all of the liability ofloosening shaft e from the rubber roll E, which is a very serious difficulty occurring in most wringcrs.

P represents a spring-clam) uniting the legs B, which go outside of the tub. It is important to know how these legs clamp against the tub. This is accomplished by means of the bent clamp I?. The tenons P are formed divergent at angles the reverse of the curve of the bow oit' thc clamp P. This angle of the tenons prevents anyy tendency ot' the spreading ofthe legs B from the strain of the clamp, and avoids the use ot' fastening devices to hold them in position, and is an important feature.

S represents a combined clamp and drainboard, which is at thc same time cheap and efficient. It fits in gains cut in the frame-piece A, and is held in position by means of clampbolt H, which passes through the ends of the board.

R represents a detachable drainboard upon the opposite side of the frame.

By my method of making the wringer-frame and uniting the parts I obtain several important advantages: First, I obtain a cheap and more durable frame 5 second, by means of the fork spring-bar L and springs m m, I obtain an easyadj ustmentof the spring,with an increased yielding capacity and durability. I also provide an improved support for the wringer frame, which also acts as an efficient clamp to hold the frame on tubs of varying sizes in a very efficient manner.

l claiml. The combination, in a wringerframe, of

`the legs B with the bow-shaped spring-clamp p, having its ends bent at an angle reversely to the curvature of the bar, and fitted into mortise formed through the said legs, substantially as described.

2. In a wringer-frame, the combination,with the clamp-rods H, of the forked bar L, and springs M, and rollers l, placed intermediate the prongs ofthe fbrlasubstantially as herein set forth.
